This lo-res, firefly-ridden render of Brasil's power transmission lines (osm and derived) took hours. Turns out even with Tyler's amazing optimizations, I can still bring the rendering process to a crawl. To be fair, it's over 150k lines.

#30DayMapChallenge · Day 26 · Transport. Yet another visualisation of global shipping density. But it's engraved on metal with realistic light and shadow. Because we can do that in R.

#30DayMapChallenge · Day 22 · Natural Earth. Many spinning globes. Honestly, I don't know how to use this amazing resource because I'm—no surprises here—not a cartographer. Am just a one-note guy who likes R.

I was there from almost the beginning. Behold my ggplot sword from 2019! This took hours to render back then.

#30DayMapChallenge · Day 21 · Icons. Lighthouses of the Pacific. Yes...I've done lots of lighthouse maps but not in this projection. I still like it—there's nothing like path-traced points of light realistically rendered.
